;; Hack to ensure that ASDF recognises the class
|
|
;; as a keyword, which I think is currently a bug.
|
|
;; If LASS is only in DEFSYSTEM-DEPENDS-ON and the
|
|
;; system tries to specify a LASS-FILE component,
|
|
;; ASDF complains about an unknown component type
|
|
;; even though the class exists. Loading LASS and
|
|
;; the system separately however works just fine.
|
|
;;
|
|
;; Since ASDF by default searches classes in
|
|
;; ASDF/INTERFACE we simply smuggle our own class
|
|
;; into that package. Sneaky, but the only sensible
|
|
;; workaround for now.
